JOSEPH HEINRICHS, OF NEW YORK, N.' Y.

COFFEE-POT.

SPECIFICATION forming 'part of Letters Patent No. 747,705, datedDecember 22, 1903.

Application filed May 6, 1901. Renewed May 4, 1903. SerialNo. 155,681.(Novmodel.)

To a/ZZ whom it may concern/t:

Be it known that LJosEPH HEINRICHS, a citizen of the United States, anda resident of New York city, county of New York,and State of New York,have invented certain new and usefulmprovements in Codec-Pots, of whichthe following is a specification, reference being had to theaccompanying drawings, form# -ing a part thereof, in which similarletters vof reference indicate corresponding parts.

My invention relates to improvements in the course of operation. y Iattain these objects by the device illustrated inthe accompanyingdrawings, in which- Figure 1 is a vertical section through my device,and Fig. 2 is an exterior elevation shown partly in section to betterillustrate a slight constructional modification.

A designates au upper compartment attached byta water-tight joint at ato a lower water-compartment B, having a draw-off cock b.

The upper compartment A is providedrwith a suitable cover a, fittingloosely upon the compartment or chamber to provide for and allow theegress and ingress of air, and the entire apparatus sets upon an openstand C, and directly beneath the compartmentor chamber B upon the baseof the stand C, I.

place any suitable heater, such as the lamp D.

The lower end of the compartment orchalnl ber A is constructed of metalin the form of 4seen in Fig. l of the drawings.

the bottom of the compartment B.' A second tube b3, open at both ends,is securely fastened intermediate its length to the bottom of the cup b'and extends upwardly into the upper compartment A almost to the top ofsame and downwardlyinto the lower compartment B, not quite as farv asthe tube b2, the lower ends of thetwo tubes lying in differenthorizontal planes, as will be clearly The cup end b is formed with aledge b4, upon which areceptacle a3, containing ground coffee or tea, isadapted to rest. The bottom ofthe coee or tea receptacle is perforatedor foraminous and has an upwardly extending sleeve b5 securely fastenedtoit, the tube b5 passing through said sleeve.

To operate my device,heat is applied to the bottom of the lowercompartment B by means of an alcohol-lamp D or other suitable means.

Steam is generated in the upper part of the compartment B and inexpanding drives the Water up through the tubes b3 and b2 into thecompartment A, where it remains until the water in the compartment Breaches the level of the end Vof the tube b3, when the steam passing upthrough the tube allows the Water to run back into the compartment Bthrough the pipe b2, iirst passing through the ground coffee containedwithin the receptacle a3.r

By the time the water has all rentered the compartment B steam againbegins to vform, and the circuit `ofthe water is repeated and continuousuntil the coffee has reached the de' sired strength, when the Iiame fromthe lamp vis reduced, so that the operation ceases and "only sufficientheatis generated to keep the coffee at'the desired temperature. Thespace a7, formed between the receptacle a3 and the bottom of the cup b',allows the water to pass very quickly through the coffee-receptacle, andthe liquid in its passage through the coffee is' thoroughly filtered.This filtering process produces a coffee that is absolutely pure andrich in flavor and is one of the features of my invention. t

In Fig. 2 I show a slight modification, in which I form the upper andlower compartments A and B integrally and securely fasten aseparating-partition c, to which is fastened the tubes b2 and b3. I formupon this separating-partition a ledge c', which corresponds to and hasthe same function as the ledge b4 in Fig. l. In this modification thecompartments A and B are necessarily made of the same material,preferably sheet metal.

I-Iaving thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a device of the class described, an upper and a lower chambersuitably connected, a cover for closing said upper chamber, a receptaclehaving a perforated bottom, adapt` ed to rest in the bottom of the saidupper chamber, a sleeve fastened to the said receptacle, and extendingupwardly into the said upper chamber, a tube fastened to and passingupward into the upper chamber and extending downwardly into the lowerchamber, almost to the bottom of the latter; the said tube passingthrough said sleeve, said tube being closed at its extreme upper end,and having a series of lateral openings at such upper end, and a secondtube fastened at one end to and extending downwardly from the bottom ofsaid upper chamber into the said lower chamber almost to the bottom ofthe same, the aforesaid lower chamber being adapted to contain a liquidwhich is forced into the upper compartment through both the tubes by theaction of the steam generated when the liquid is heated to theboiling-point, substantially as set forth.

2. The combination of a plurality of chambers, one superposed uponanother, a coffeecontaining receptacle positionedin one of saidchambers, a tube secured at its upper end to the bottom of the upperchamber, and terminating near the bottom of the lower chamber, and asecond tube extending from a point near the bottom of the lower chamberto a point near the top of the upper chamber, said second tube beingprovided with a series of lateral oriiices, the construction being suchthat a liquid may be sprayed upon the material in the receptacle throughthe orifices in the tube, and simultaneously forced up the tube which issecured at its upper end to the bottom of the upper chamber, and upwardthrough the material in the receptacle, substantially as set forth. A

3. The combination of a plurality of chambers, one superposed uponanother, a coecreceptacle having a foraminous bottom, a sleeve extendingupward from said foraminous bottom, a tube extending from the lowerchamber through the sleeve into the upper chamber, said tube havingoriiices formed near the upper portion thereof for causing liquidascending the tube to be sprayed upon the material in thecoffee-receptacle, and means for conducting the liquid from a pointbelow said receptacle upward and through cle designed to contain thematerial from which the decoction is to be made, means for conveyingliquid from the bottom of the casing upward through the material intothe receptacle, and means forsimultaneously spraying liquid from a pointabove the receptacle downward upon the material therein, substantiallyas set forth.

6. In a device of the class described, a receptacle provided with aforaminous bottom, means for conducting liquid to a point above thereceptacle and spraying such liquid down upon material in thereceptacle, and means for directing the liquid upward through theforaminous bottom and through the material in the receptacle,substantially as set forth.

7. The combination of an upper and lower chamber, connected by ahermetically-sealed joint, a coffee-receptacle located in the bottom ofthe upper chamber, a tube secured to and extending downwardly from thebottom of the upper chamber into the lower chamber and terminating at apoint adjacent to the bottom of the same, a second tube secured to thebottom of the u pper chamber and extending upwardly through thecoffee-receptacle into the upper chamber and downwardly into the lowercham ber, said tube having passageways therein for the escape ofascending liquid, the construction being such that said liquid will besprayed downwardly upon the coffee in the receptacle, substantially asset forth.

S. The combination of an upper and lower chamber, connected by ahermetically-sealed joint, a'coifee-receptacle adapted to seat upon aledge formed on the upper chamber a short distance from the bottom, theconstruction being such that a space is formed between thecoffee-receptacle and the bottom of the upper chamber, a foraminousbottom for said coded receptacle, a tube secured to and extendingdownwardly from the bottom of the upper chamber into the lower chamber,a second tube secured to the bottom of the upperchamber, and extendingupwardly through the coffee-receptacle into the upper chamber, anddownwardly into the lower chamber, said tube having lateral orificestherein for the escape of liquid ascending tube from the lower ICOreceptacle, a portion of lsaid liquid passing ence of two witnesses,this 29th day of April,V through the first mentioned tube upward i 1901.Y throughthe foralninous bottom of the recepv taole, and means forheating the liquid in the JOSEPH HEIN HIGHS '3 lower chamber,substantially as set forth.
